Microbes and Other Elemental Cycles01:24

Microbes and Other Elemental Cycles

Microbial activity plays a pivotal role in the biogeochemical cycling of iron and manganese, especially at the redox gradients characteristic of stratified aquatic environments. These cycles are driven by microbial transformations between oxidized and reduced forms of the metals, allowing organisms to exploit them for metabolic energy and structural purposes.Iron Cycling Across Redox GradientsIn neutral, oxygen-rich surface waters, iron is predominantly found in its oxidized, insoluble ferric...
Acid Mine Drainage01:19

Acid Mine Drainage

Mining activities that disturb sulfide-rich rocks, particularly those containing pyrite (FeS₂), initiate a cascade of geochemical and microbiological processes with serious environmental implications. When exposed to air and water, pyrite undergoes oxidation, releasing sulfate, ultimately forming sulfuric acid and mobilizing heavy metals into surrounding water systems. This phenomenon, known as acid mine drainage (AMD), results in low pH waters laden with toxic elements that threaten aquatic...
Other Unique Bacteria01:18

Other Unique Bacteria

Magnetic bacteria exhibit a directed movement called magnetotaxis, driven by structures called magnetosomes. These magnetosomes consist of chains of magnetic particles made of either magnetite (Fe₃O₄) or greigite (Fe₃S₄) and are organized in a linear conformation by a protein scaffold within invaginations of the cell membrane. The bacteria align along the north–south magnetic field lines, much like a compass needle. They are typically microaerophilic or anaerobic and are commonly found near the...
Microbial Mats01:25

Microbial Mats

Microbial communities forming biofilms and mats represent complex, spatially structured ecosystems where metabolic processes are stratified according to light, oxygen, and nutrient gradients. Biofilms are initial colonization stages, only a few millimeters thick, while mature microbial mats can reach centimeter-scale thickness and display intricate vertical organization. Their structural and functional heterogeneity allows microorganisms to occupy distinct ecological niches within a few...
Metal-Ligand Bonds02:51

Metal-Ligand Bonds

The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...
Radical Oxidation of Allylic and Benzylic Alcohols01:21

Radical Oxidation of Allylic and Benzylic Alcohols

Activated manganese(IV) oxide can selectively oxidize allylic and benzylic alcohols via a radical intermediate mechanism. Primary allylic alcohols are oxidized to aldehydes, while secondary allylic alcohols yield ketones. The redox reaction of potassium permanganate with an Mn(II) salt such as manganese sulfate (under either alkaline or acidic conditions), followed by thorough drying, yields the oxidizing agent: activated MnO2. While MnO2 is insoluble in the solvents used for the reaction, the...

Summary

Gossia species can accumulate multiple metals, not just manganese (Mn). These metals are stored in different leaf tissues, indicating varied detoxification strategies in plants.

Area of Science:

  • Plant Biology
  • Biogeochemistry
  • Ecology

Background:

  • Australian Gossia species exhibit a strong affinity for manganese (Mn), a vital micronutrient for photosynthesis.
  • Some Gossia species are known Mn hyperaccumulators, with Mn uniquely concentrated in photosynthetic cells.
  • Recent findings suggest these species accumulate metals beyond Mn, prompting further investigation.

Purpose of the Study:

  • To investigate whether the primary sequestration of metals in photosynthetic tissues is exclusive to Mn in Gossia species.
  • To explore the microdistribution patterns of excessively accumulated foliar metals in Gossia species known to accumulate nickel (Ni) or aluminum (Al) in addition to Mn.

Main Methods:

  • Field sampling of Gossia species known for accumulating Mn, Ni, or Al.
  • Utilizing combined proton- and electron-probe data.
  • Evaluating in vivo microdistribution patterns of foliar metals.

Main Results:

  • Gossia fragrantissima accumulates zinc (Zn) and cobalt (Co) alongside Mn and Ni. Mn, Ni, and Co are localized in mesophyll cells, while Zn is in the upper epidermis.
  • In G. hillii, Mn concentrates in palisade cells, and Al is found in the epidermis.

Conclusions:

  • The primary disposal of excess foliar metals in photosynthetic cells is not limited to Mn.
  • This study provides novel intrageneric insights into metal compartmentation within Gossia.
  • Significant variations in tonoplast metal transporters involved in detoxification are suggested.
